(Cl. 222-25) The inventionrelates to a unit which is particularly designed for a variableproportioned charging and pressure delivery of a carrier liquid with adetergent material to be applied therewith.

Understanding that liquid-borne detergents of different strengths areused extensively in domestic and industrial cleaning operations indifferent concentrations, a particular purpose is to provide an improvedunit for variably charging water, or other liquids, with a detergent,and effecting a pressure discharge of the charged liquid at a desiredpoint of use therefor.

Another object is to provide a movable detergent-discharging unit whichis arranged to deliver a detergentcharged carrier liquid therefrom at asuper-atmospheric pressure, whereby surface-cleaning operations may becompletely effected and completed solely by the application of a jet ofthe charged liquid against work surfaces to be treated.

An added object is to provide and effect a delivery of a charged oruncharged carrier liquid at a preferred regulated and relatively highpressure.

A further object is to provide a dispensing unit of the characterdescribed which is arranged to utilize water received at normal supplypressures from a piped domestic or industrial supply as a carrier for amaterial to be applied therewith.

Yet another object is to provide a unit of the character describedincluding means for periodically and independently testing theoperativeness of certain valves of the unit which are designed toprevent back-flow into a liquid-supply system providing potable Water asthe carrier liquid.

A still further object is to provide a unit of the character describedwhich is adaptable for its general use in mixing non-aqueous solventsand/ or other carrier liquids with other than detergent materials.

The invention possesses other objects and features of advantage, some ofwhich, with the foregoing, will be set forth or be apparent in thefollowing description of a typical embodiment thereof, and in theaccompanying drawings, in which,

FIGURE 1 is a perspective view of a typical floormounted embodiment ofthe present dispensing unit as viewed generally from an upright cornerthereof.

FIGURE 2 is a perspective view of the unit as viewed from the cornerthereof which is diagonally opposite that of the view of FIGURE 1.

FIGURE 3 is an enlarged side perspective view showing the uncovereddispensing means and flow circuit of the present unit.

FIGURE 4 is a top perspective view of the mechanism shown in FIGURE 3.

FIGURE 5 is a schematic view of the apparatus as provided with a pair ofseries-connected check valves in a carrier-liquid supply line to theunit and arranged for normally and independently preventing a back-flowdischarge of a detergent-charged liquid from the unit, and including ameans for testing one or both of said check valves for any back-flowleakage therethrough.

FIGURE 6 is an enlarged fragmentary View indicating an arrangement forindividually checking the operativeness of one or tWo check valves ofthe circuit portion leading to the unit from the external solventsupply.

FIGURE 7 is a view corresponding to that of FIG- URE 6 and indicating anarrangement for checking the operativeness of the other check valve ofthe circuit portion leading from the external liquid supply to the unit.

As particularly illustrated, a present unit 11 is of a wheel-mountedroll-around type for use in providing and forcibly applying a liquid atworking points adjacent the unit, and said unit generally comprises abase portion 12 supporting the operative mechanism of the unit andcomprising a rectangular tank 13 having a reservoir space 13 for aliquified material 14 to be provided therefrom for its forcibleapplication at a working point. In the present structure, the top wall13 of the tank 13 directly carries the operative mechanism of the unit,and the tank thereby directly comprises the support frame for saidmechanism in a base structure which is of minimum weight for its duty. Afiller nozzle 15 extends obliquely upwardly from the tank space 13 at anend thereof and is normally closed by a vented filler cap 15' for aconstant provision of atmospheric pressure within the otherwise closedtank space 13 in which a charge of the material 14 to be applied by theunit is maintained.

It will now be noted that a rigid suction pipe or conduit 16 leadsupwardly from its intake end in a suitable sump or well provided in thebottom of the tank 13 to the suction connection of a mixing injector 17of the venturi-tube type having an intake connection for aninjector-operating liquid and a discharge connection from the injector.A rigid pipe or conduit 18 extends to the injector connection from aflexible supply hose or conduit 19 through an adjustable primary supplyvalve 20, and the liquid supplied through the valve 20 is provided at arelatively low pressure, and would usually comprise water from adomestic or industrial supply line. A rigid pipe or conduit 21 leadsfrom the injector discharge connection to the intake of a suitable pump22 driven by the shaft 23' of an electric motor 23 and arranged todeliver the liquid received by it at a relatively high pressure to andthrough a rigid pipe 24 connected by a flexible hose or conduit 25 witha suitable discharge nozzle 26 for the liquid received from the injectorand supplied through the pump at a relatively high pressure to thenozzle having its discharge rate adjustable from zero to a maximum.

As particularly shown in FIGURE 5, the suction pipe 16 leading from thereservoir space 13' is provided, in order, with a trap 27 for collectingany solid particles from the material 14, a check valve 28 which isoperative to prevent a return of the material 14 to the space 13' and a:manually adjustable flow-control valve 29, said valves and trap beingconveniently provided in a portion of the pipe 16 which overlies thesupporting tank 13. An automatic pressure regulator 31 is provided forcontrolling the flow rate of liquid passing to the injector through thepipe 18 beyond a valve 30 in the pipe 18, and the portion of the pipe 18between the valves 20 and 30 is provided with two mutually spaced checkvalves 32 and 33 connected in series and designed to operateindependently and positively to prevent a back-flow of liquid to thesupply pipe 19. A pressure gauge 34 is connected with the pipe 21 fromthe injector 17 to the pump 22, and a pressure gauge 35 is connected atthe end of a branch 24 of the discharge pipe 24 for the pump, thearrangement being such that the effective suction pressure of the pumpand the effective discharge pressure from the pump may be constantlyascertained.

The automatic actuation of the motor 23 to operate the pump 22 isarranged to be effected in accordance with the pressure in the conduitof the branch pipe 24' which is intermediately connected with andcontrols a suitable adjustably settable single-pole pressure-operatedelectric switch 36 of a suitable structure for the purpose, with saidswitch being shown as represented by its casing and arranged for itsadjusted setting in accordance with a variable determination of itsopening pressure by an adjusting knob (not shown) of the switch. Thecontacts of a terminal plug 38 of an electrical two-wire ex tension cord39 are arranged to supply motor-operating power through a suitabledouble-pole switch 40 to the series-connected pump motor 22 andpressure-operated switch 36, and the arrangement is essentially suchthat the power to the motor is cut off when the pressure at the closednozzle valve exceeds a predetermined value as determined by the settingof the pressure-controlled switch 36, the motor circuit being energizedto provide a pumped supply of liquid at the adjustable nozzle 26 as longas the nozzle valve is open.

A means is preferably provided for variably proportioning the amounts ofcarrying and charging liquids delivered to the pipe 21, and said meansessentially comprises a suitably valved by-pass pipe 41 connected by Ts42 and 43 respectively provided in the pipes 18 and 21; as shown, the T42 is connected in the pipe 18 between the regulator 31 and the injectorconnection while the T 43 is interposed in the pipe 21 between theconnection for the gauge 34 and the injector connection. A manuallysettable flow valve 44 is interposed in the bypass pipe 41, and isadjustable to provide for any desirable variable proportioning of thecharging and carrying liquids in the mixture delivered to the pump 22 upto a limit of about 1 to 45 when the valve 44 is fully closed.

It will be understood that the relation of the valved by-pass pipe 41 tothe liquid flow to the pipe 21 beyond the T 43 therein is such that,when the valve 27 is fully open and the valve 44 opened to an adjusteddegree, an adjustably proportioned mixture of the carrying and chargingliquids is deliverable to the discharging nozzle 26 by the pump 22. Onthe other hand, if the by-pass valve 44 is fully closed while the valve27 in the suction pipe 16 is fully open, the resulting mixture deliveredto the pump contains a maximum amount of the charging liquid providablein accordance with the pump action. Alternatively, if the valve 27 isclosed, and the valve 44 is either open or closed, only the carryingliquid received from the hose 19 will be delivered at the nozzle 26, asfor rinsing operations in lieu of the delivery of a charged liquid fromthe applying nozzle 26.

Referring generally to the functioning of the described assembly, itwill now be noted that a closing of the nozzle valve while the unit isoperating to deliver a mixture of the liquids will create an appreciableback-pressure tending to force the liquid mixture back into the flowline of the pipe 18 and the supply hose 19, and that the check valves 32and 33 are provided for normally preventing such a back-flow which ishighly undesirable, if not dangerous, since it might charge the supplyline to the hose 19 with the detergent 14, or other chemically activecharging liquid, for its escape to other portions of the supply systemproviding water or another potable carrier liquid. However, since thecombined seal normally providable in the supply pipe 18 by the checkvalves 32 and 33' while the valves 20 and 30 are open might fail as tosaid valves to thereby provide back-pressure leakage into the supplyline 19, a means is provided for collectively or independently checkingthe functioning of the valves 20 and 30 and 32 and 33 if a back-pressureleakage to the supply line represented by the hose 19 connecting thepresent unit with a domestic or industrial liquidsupply system issuspected or known.

To provide for the desirable leakage testing of the valves 20 and 30 andthe check valves 32 and 33, pipe T fittings 45 are interposed in thepipe 18 ahead of the valve 20, between the valve 20 and the check valve32, between the check valves, and between the check valve 33 and thevalve 30. The respective Ts 45 mount suitable normally-closed hose-bibfaucets 46 and 47 and 48 and 49 on their stem portions, and the hose-bibnozzles of the different faucets are arranged for their variableselective connection by means of flexible hose elements provided withterminal couplings for threadedly and sealedly connecting the hoseelements with and between the hosebib nozzles of different pairs of thefour different said faucets, with FIGURE 5 showing the end faucets 46and 49 so connected by a hose 52.

By particular reference to FIGURE 6, a hose element 53 is shown asconnecting the bibs of the faucets 48 and 49 whereby, while the shut-offvalves 20 and 27 in the pipes 18 and 16 respectively are closed, anopening of the connected faucets for a by-pass flow about the checkvalve 33 of any charged or uncharged carrier liquid is provided, and asubsequent opening to the atmosphere of the faucet 47 underback-pressure conditions in the supply line 18 beyond the closed valve20 and the open valve 30 will permit the back-pressure escape from saidfaucet of any liquid which has leaked through the check valve 32 forindicating by a liquid discharge from the opened faucet 47 a functionalfailure of the valve 32 as a check valve. FIGURE 7 discloses a hose 54as connecting the hose-bibs of the faucets 47 and 49 whereby, with thevalve 20 closed and the valve 30 open, an opening of the hose-connectedfaucets 47 and 49 provides for a functioning of the connecting hoseelement 54 to by-pass the check valves 32 and 33 to provide for testingthe functioning of the valve 33 by opening the faucet 48 after the fullpressure-holding functioning of the other check valve 32 has beenestablished following its testing in the manner taught respecting theassembly of FIGURE 6.

With further reference to FIGURE 7, it will be noted that the primarysupply hose 19 which connects the intake pipe 18 with the pressuresupply source of the carrier liquid would extend from a closableconnection (not shown) of and with said source, so that this arrangementis further adapted for use in testing the functioning of the closedsupply valve 20 of the present unit when said connection is closed,whereby, with the check valves 32 and 33 by-passed by the hose 54 andthe faucet 43 closed, a discharge of liquid from the opened faucet 46would indicate a back-pressure failure of the closed valve 20. Thechecking of the operativeness of the valve 33 may also be effected withthe arrangement of FIGURE 5 which also provides for a by-passing of thevarious valves 20 and 32 and 33 for facilitating the removal thereof forany repair or replacement required. Also, if desired, it is a simplematter to test the functioning of the closed flow valve 30 by connectingthe faucets 46 or 47 with the faucet 48 by a hose, and then opening thefaucet 49 to ascertain any back-pressure leakage of this valve. Althoughthe present test-hose elements 52 and 53 and 54 are shown as ofdifferent lengths, it will be understood that the longer hose element 52may comprise the only hose element needed and provided with the presentunit.

Since a present unit for charging an externally supplied carrier liquidwith a liquified detergent or other material supplied from the reservoirtank 13 of the unit and for dispensing the mixture from the unit, and isof the rollaround type for its variable use positioning movement on asupporting fioor in more-or-less dusty spaces, the mechanism of the unitcarried on the top tank wall 13" is preferably enclosed within a coverelement 61 suitably mounted on the tank-providing base portion 12 of theunit. The present cover element 61 is of generally rectangular outline,is open at its bottom, is arranged for its removably supportedandsuitably fixed and fitted mounting upon the top of the base portion12 with its sides generally registering with the sides of said portions,and provides a facilitated access to certain parts of the unitmechanisms which are desirably available during its setting-up and use.

As particularly shown in FIGURE 1, the end 62 of the cover 61 disposedadjacent the motor 23 is notched out from its bottom edge for theextension of the tank filler nozzle 15 beyond it and provides a notch 63extending from its bottom edge and arranged for the free extension ofthe pipe 18 from its releasably coupled connection with the supply line19 into the cover space. A longitudinal cover side 64 is provided with anotch 65 extending from its bottom edge opposite the two-way powersupplyswitch 40 for the motor to facilitate the connecting and disconnectingof the terminal plug 38 of the power-supplying extension cord 39 to theswitch assembly, is provided with a bottom notch 66 at which the handlesof the valves 27 and 44 are exposed for their turning, and is furtherprovided with a sight opening 67 opposite the dial faces of the enclosedgauges 34 and 35 to facilitate pressure readings thereof. Also, a notch68 extending from the bottom of the other cover end 69 freely receivestherethrough the pipe 24 from which the nozzle-supplying delivery hose25 extends in releasably coupled relation to it.
